RALPH R. BARBER, OF HARRISON, ARKANSAS.

ENVELOP.

Specification of Letters Patent. Patgnt gdl M 211 11916.

Application filed June 1, 1915. Serial No. 31,516.

To all whom it may concern: I

Be it known that I, RALPH R. BARBER, a citizen of the United States, residing at Harrison, in the county of Boone and State of Arkansas, have invented certain new and useful Improvements in Envelops; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

My invention relates broadly to improvements in stationery, and more particularly to envelops, the objects of the invention being to provide a device of this class having a ripping cord so secured in position as to prevent the envelop from being accidentally ripped, and to improve upon the sealing means for the device.

With the foregoing ends in view, my invention consists of certain novel features of construction hereinafter claimed and fully described by reference to the accompanying drawings wherein:

Figure 1 is a perspective view of the blank of paper from which one form of the envelop is constructed; Fig. 2 is a similar view with three of the numerous flaps to be described folded to active position; Fig. 3 is a third perspective view illustrating the complete device ready for sealing; Fig. 4 is yet another perspective showing the envelop sealed and ripped partially open by the ripping cord;'Fig. 5 is a perspective view of a slightly different form of the invention; Fig. ,6 is a'similar view showing two flaps to be described folded inwardly to active position, and Fig. 7 is an additional perspective view illustrating the envelop completed for use.

In these drawings whichconstitute a part of the application, the numeral 1 designates the rectangular front of the envelop having at its upper edge the sealing flap 2 provided at its center with a tab 8, the edges of such tab as well as those of the flap 2 being coated with glue or other viscous material 4: on their inner side. Extending from the upright edges of the front 1, are the flaps 5 which are folded inwardly to the position shown most clearly in Fig. 2, when the envelop is folded for use by an appropriate machine or by hand. Extending from the lower edge of the front 1 is the flap member 6 which constitutes the back of the envelop, such back preferably being of less width and height than the front 1 as disclosed most clearly in Fig. 3, and having along its edges a coating 7 of glue or the like which unites the inwardly folded flaps 5 with the back 6 when the device is folded.

The free upper edge of the back 6 is provided with a cord anchoring flap 8 preferably having thereon a tab. 9, the edge portion of the latter as well as that of the former being given a coating 10 of adhesive material. Before folding the back 6 to active position, the flap 8 is folded inwardly thereon and adhered thereto by the material 10, whereby a ripping cord 11 may be effectively anchored between said flap 8 and the back 6, at the fold connecting the two. Whennow the back 6 is folded into parallel relation with the front 1, the upright edges of said back are adhered to the inturned flaps 5, the ripping cord 11 will be disposed below the upper edge of the front 1 (see Fig. 3). This is important, since when the sealing flap 2 is folded downwardly upon the back 6 and secured in this position by the material 4, the cord 11 will not be disposed in contact with the fold connecting the front 1 and flap 2. Thus it will be evident that should said cord be accidentally pulled, only the fold in which it is secured will be torn and'not that connecting the sealing flap'2 and the front 1, that is pro vided it only be pulled to a rather small extent. Furthermore, a double thickness is provided, which must be torn by the cord 11, thereby preventing the envelop from being easily opened.

In connection with the parts above described, I prefer to provide the back 6 and the flap 8 contacting therewith, with alined slots 12 into which the tab 3 is inserted as disclosed in Fig. 4, thus serving as means supplementing the material 4, for securing the sealing flap in active position.

In Figs. 5, 6, and 7 ,"the construction of the device is considered as being identical with that previously described with the exception that in addition to the flap 8 (identical with the flap 8), the flap members onthe ends of the front, designated in these figures by the numerals 5 are provided on their lower ends with cord anchoring flaps 0r tabs 8* which, whenthe device is folded for use, are folded upwardly upon the flaps 5 and are adhered to the front 1 by mucilage or the like 5*, the ripping cord 11 I considerable stress must be placed upon this cord to produce the desired effect, due to the double thickness through which it must tear at the corners of the envelop.

From the foregoing description, taken in connection with the accompanying drawings, it will be evident that although very simple construction has been provided for the attainment of the desired ends, the im proved envelop will be very efficient in operation and may not be easily torn at its corners, regardless of the fact that ripping cords are used.

I claim:

An envelop having flaps formed on the additional flap is folded; in combination with a ripping cord anchored invthe fold of the cord anchoring flap.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
